Why did the British Parliament decide on a coup d’etat?

At that time, King Charles 1 wanted to strengthen his power and limit the parliament. In this connection, this caused an internal conflict between them. Parliament realized that this was a chance for him to suppress the royal autocracy and strengthen his position in the country. A civil war was unleashed, which took place from 1642 to 1649. During this time, the king was twice severely defeated. Ultimately, he fell into the hands of parliament, and after a while he was executed.
